Internal Wire Upgrade for SME V

No, you don't have to. It's not necessary, you'd better upgrade a cartridge. Silver is not better than Copper even if you want to believe it is better. 

Thank you Chakster! Keegiam, unless a wire is broken leave well enough alone. The SME is a fine tonearm. All tonearms are relatively delicate devices. It is not hard to injure a bearing. If that happens you have a Christmas tree ornament. 

Chakster and mijostyn, the wiring would be replaced by the service expert as part of his installation of my new AT cartridge.  I haven't seen anything in the forums suggesting that a professional has ruined a tonearm during a service like this.
Do you still recommend against replacing the internal wiring?  I have seen numerous comments that the wiring used in the early SME V's was one of its few weaknesses.
